We found Working The Room, Practice The Behaviours You Want, and Entry and Exit Strategies enormously powerful.
The title of this HOW2 says it all. If you want certain behaviours in your classroom, then don’t expect them to happen jus because you ask for it. Like any habit, it takes practice and repetition.
We’re used to the idea of practising a physical skill in sports, or a procedure in an academic subject, yet seem to find it odd to do the very same thing with classroom behaviour. But by being very clear about your expectations and giving students a chance to embed the habit, you are sending out strong messages about your standards.
